Phys.org / Quantum squeezing sidesteps the limits on mechanical transducers
From detecting the ripples of colliding black holes to imaging individual chemical bonds, mechanical transducers have repeatedly transformed our understanding of the universe. So far, however, the sensitivity of these devices ...
Medical Xpress / Exposure to bright evening light linked to higher risk of age-related eye disease
Every sunrise and sunset sends the body a signal, keeping the circadian clock running on a roughly 24-hour cycle. This clock evolved so organisms could adapt to Earth's daily rotation, syncing their biology to the pattern ...
Phys.org / Quantum gravity research links continuous parameters to local operators within the theory itself
A researcher at Kyushu University and his collaborators have shown that continuous parameters in quantum gravity may not be freely adjustable "dials" from outside the theory, but rather arise from operators within the theory ...
Phys.org / Why female guppies prefer rare males and how this might shape evolution
When it comes to choosing a partner, some species prefer males that stand out from the crowd. Evolutionary biologists call the resulting process negative frequency-dependent selection. It means that a male has a huge mating ...
Phys.org / Artificial DNA tiles could deliver drugs and monitor neurons non-disruptively
Living cells constantly exchange ions (i.e., charged particles) via the thin barrier that surrounds their interior, known as the outer membrane. Neuroscientists and medical researchers have long been trying to devise effective ...
Phys.org / Asteroid zooming past Earth on Saturday visible to stargazers
A large asteroid that will zoom harmlessly past Earth on Saturday will be visible to stargazers using a small telescope or large binoculars, the European Space Agency announced Wednesday.
Phys.org / Interlayer self-doping could unlock room-temperature multiferroics in atom-thin materials
Multiferroics are materials that exhibit more than one prominent "ferroic" property, such as ferromagnetism and ferroelectricity. One of their most advantageous features is that they allow engineers to control their magnetic ...
Phys.org / Lavatory shaft reveals the cost of 17th‑century vanity in Germany
Four goose skulls were pulled from a former toilet shaft in Brandenburg, Germany, each of them riddled with strange holes. As it turns out, these holes were the telltale signs of fancy feathered crests, making them the first ...
Science X / AI in the classroom: Are we building better thinkers or better shortcuts?
AI chatbots like ChatGPT have made their way into college life, sparking an important debate: Do these tools actually help students become better thinkers, or are they just a shortcut? Universities want to foster critical ...
Phys.org / Horizon edge states gain finite description in string theory calculation
Modern physics theories highlight the key role of horizons—boundaries beyond which information cannot reach an observer—in a variety of cosmological and gravitational phenomena. Two renowned examples of these boundaries are ...
Phys.org / Antarctica is offering 30 to 50 years' worth of warning on sea level rise, models suggest
Scientists predict that the next three to five decades provide a critical window to anticipate and plan for Antarctic ice loss and its contribution to sea level rise. Research published in Nature, led by Monash University ...
Phys.org / Oldest example of preserved tube feet reveals clues about the lives of 452-million-year-old sea lilies
Echinoderms, such as starfish, sea urchins and sea lilies, use small, flexible, tubular projections called "tube feet" for locomotion, feeding, respiration and sensory perception. Crinoids, a subgroup of echinoderms, are ...
